Thesis defense refers to the process of oral defense to the designated expert group or teacher group after graduate students finish their degree thesis. In the defense, graduate students need to explain and answer their own papers, research methods, conclusions and other issues, in order to show their research results and accept the evaluation and opinions of expert groups or teachers. After the defense is passed, graduate students can get the corresponding degree.

Thesis defense is an important link for graduate students to complete their dissertations, and the following points should be noted:

1. Prepare in advance: know the time and place of the defense, the number of judges and the scoring standard in advance, and fully prepare the materials and materials needed for the defense.

2. Dress appropriately: dress appropriately, try to avoid dressing too casually or formally, and keep it neat, clean and comfortable.

3. Expression of self-confidence: Show self-confidence in your defense, don't be nervous, and don't be too modest. Answer questions clearly, concisely and accurately.

4. Pay attention to language: pay attention to the standardization and accuracy of language, and don't use colloquial, dialectal or too uncommon words.

5. Respect the judges: In the defense, we should respect the judges, listen to their questions and opinions carefully, and do not argue or resist.

6. Pay attention to time: pay attention to time control in defense, and don't delay or overtime.

7. Summary: At the end of the defense, it is necessary to summarize and express the feelings and gains of the defense, as well as the prospects and expectations for the future.

8. Familiarity with the thesis: Familiarize yourself with your thesis before the defense, and have a deep understanding and preparation of the key parts and difficult issues in the thesis, so as to be able to answer the judges' questions.

9. Don't plagiarize: Don't plagiarize other people's opinions and research results in your defense, which will not only seriously affect the defense results, but also leave a stain on your academics.

10. adopt suggestions: after the defense, the jury will put forward its own opinions and suggestions, and graduate students should listen carefully and adopt reasonable suggestions in order to improve their thesis level.

In a word, thesis defense is an important link after graduate students complete the duplicate check of their dissertations. Students need to be fully prepared, express themselves confidently, respect the judges and pay attention to time and language in order to successfully pass the defense and obtain a degree.
